This adapter allows you to use the rogerquin spool holder designed for the Sovol SV06: https://www.printables.com/model/409684-spool-holder-for-sovol-sv06-3d-printer with the stock SV06 Plus bearing spool holder. It is simply a smaller version of the end of the SV06 Plus spool. Unscrew the original end cap and screw this one on. Prints without supports.
I found that removing the bearings from the stock spool entirely works best. With the bearings installed, it spins too freely, both in its stock form and with the rogerquin spool holder. Removing the bearings gives just the right amount of resistance without allowing the spool to unwind itself.
The author marked this model as their own original creation.
